"We constantly review our operations and contingency planning, liaising with central and local government, emergency services and other agencies.
"We also use a wide range of overt and covert policing tactics. Covert tactics, by their nature, are not obvious to the public, but overt tactics include the deployment of high visibility policing at a variety of locations."
